Battery Doctor is a free application available in App Store.
With battery doctor you can manage your phone and save necessary time life , in few simple options :
power saving modes for work/class/sleep and more
In the saving mode we are able to chose modes – and even add own customized modes for different purpose.
As you can see we have 3 modes coming with the App : default mode , super saving and silent mode.
Just to clarify – between default mode and super saving mode there’s more then 2 hours difference in the battery time life !!
In the Schedule mode we can choose between 3 modes : sleep mode , class mode and work mode. we are able to define specific hours for each mode , and the modes will change automatic.
Task Killer – kills tasks with one click – Disable unnecessary apps that drain your battery
The Task killer – is the most useful and easiest tool to use.
By clicking “Save Power” – the app will diagnose issues in the phone , and let us optimize it.while optimizing, battery doctor cancel apps , documents we don’t use at this moment , etc.
